In Grails, I like to have a many-to-many relation among entries of the same domain class Person. Relations will link to different persons the "leftPerson" and the "rightPerson" since the "Parent-child" and "Employer-Employee" relations will discriminate the position of each link. That I would like to have is something like the following...
I'm somewhat new to Grails. As I create or update domain object and fire save() or validate() on an object, if the method fails, the system does not seem throw an exception.

In our grails application we're logging a lot, but need a mechanism to associate all of those messages with the request/response being processed. It has proven easy enough to generate a request UUID, but now I'd like that id appended to each log message generated within a request context without passing that id within each log message. ...

I'm writing a multi-threaded application in Grails and the additional threads need access to GORM/Hibernate. When they try to access GORM I get the error "org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here".

When I change a domain object, rather than updating the database record, I'd like to archive the old record record and create a new one. I'd like to force GORM to do this automatically. For example, if I had this domain class: class User { String username String email Boolean active } then I'd like user.email = email us...

The view will look like a tabbed browser, w...

Is there a way of intercepting all new Hibernate sessions when they're created? I need to access each Session instance to enable a Hibernate filter with a parameter. The only solution I've gotten working has involved wrapping the SessionFactory, but this involved a lot of semi nasty hacks as well as it required me to implement around 6...
